[Renovascular hypertension and Takayasu disease]

We present three cases of Takayasu disease which were peculiar because all three of them first manifested as vasculorenal hypertension. The pathogenic mechanisms of hypertension in this disease are reviewed, being renal arteries stenosis the most important mechanism. The great prognostic and therapeutic implications of hypertension in these patients made us suggest the performance of arteriographies of supraaortic trunks in all cases of vasculorenal arterial hypertension associated to certain clinical, analytical and/or arteriographic criteria which are mentioned.
